I say he will likely always tear up.
I was a fencer back in college. I competed at a very high national level with some rather unlikely international aspirations that were never tested.....damn you Jimmy Carter.
The level of effort, sacrifice, and emotion that goes into competing at that level is unfathomable to anyone who hasn't actually experienced it. When/if that effort and sacrifice finally pays off with a result that you've always dreamed of, but never really knew would happen, the emotion is enormous. In my experience, there are those that tear up and those that don't. I'm not terribly embarrassed to say that I was in the former camp myself.....as were a LOT of my fellow competitors, men and women.
